AD8619WARUZ-RL

Overview

The AD8619WARUZ-RL is a quad, low-cost, micropower, low-noise CMOS operational amplifier with rail-to-rail input and output capabilities. It operates from a single supply of 1.8 V to 5.5 V or dual supplies of ±0.9 V to ±2.5 V. Key electrical specifications include a maximum offset voltage of 2.2 mV, a maximum input bias current of 1 pA, and a gain-bandwidth product of 400 kHz. The device consumes a maximum of 50 μA per amplifier over the temperature range. It is housed in a 14-lead TSSOP package and is qualified for automotive applications under AEC-Q100 standards.

Feature Summary

• Rail-to-rail input and output operation enables full signal swing compatibility with CMOS ADCs and DACs in low-voltage systems.
• Micropower consumption combined with low noise characteristics makes it suitable for portable and battery-powered instrumentation.
• Automotive qualification ensures reliability and controlled manufacturing for demanding automotive environments.
• Unity gain stability without phase reversal simplifies circuit design across various configurations.

Applications

• Battery-powered instrumentation
• Multipole filters
• Current shunt sense
• Sensors
• ADC predrivers

Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel quantity. Ensure the component meets the required automotive qualification standards if used in vehicle electronics. Check the latest datasheet revision for any updates to electrical specifications or thermal resistance values before finalizing the design.

Selection Notes

Select this component when a quad amplifier configuration is required with minimal power consumption and low noise performance. It is ideal for single-supply systems operating between 1.8 V and 5.5 V where rail-to-rail signal handling is necessary. Consider the 14-lead TSSOP package constraints for PCB layout and thermal management.

Part Context

This part belongs to the AD8613/AD8617/AD8619 family of precision amplifiers. While sharing core architectural features, the AD8619 specifically provides four independent amplifier channels in a single package. The 'W' suffix indicates automotive qualification, and 'RUZ' denotes the 14-lead TSSOP package with RoHS compliance.

Replacement Considerations

The AD8619ARUZ-RL is the commercial grade equivalent without automotive qualification. Other family members like the AD8617 offer dual channels, and the AD8613 offers a single channel in smaller packages. Verify pinout compatibility and electrical parameter differences when substituting.
